Cupboard Drawer Handles, Upcycle Vintage Industrial Drill Bit Tool Style x15

Fifteen vintage or vintage style used handles, would be superb for an industrial style upcycle project with their drill bit style design, they are not brand new, I think there's a bit of age to them and there's a slight patina that adds to the look, they are almost 21cm in length. The bolts come with them, two lengths for each, one I think would be for kitchen cupboard thickness, the other length being about 1cm longer
